What is the difference between an atom and element?
Atoms are the building blocks of everything; they are made up of neutrons, protons, and electrons (and recently it has been discovered that these 3 things are made of quarks). Each atom is one piece on its own, floating around and attaching to other atoms.An element is a substance that is made up of only one type of atom. Once the atoms cling to each other they form different substances; if only one type of atom (which means that all atoms have the same number of electrons) is combined then it forms an element. If multiple different atoms cling together it forms other substances.Ex) When atoms with only 1 electron gather they form the element HydrogenWhen atoms with 8 electrons gather they form the element OxygenWhen 2 atoms with only 1 electron cling to one atom with 8 electrons, you end up with 2 Hydrogen atoms that have now mixed with 1 oxygen atom which forms the compound H2O or water; this compound (water) is no longer an element.
Who said that each element is composed of extremely small particles called atoms?
Someone Rutherford.
Who said that all atoms of an element are identical in size mass and other properties?
John Dalton
Who proposed each element is composed of extremely small particles called atoms?
i think Dalton said it
What is it called when an electron has 8 electrons in its outer shell?
when an element has 8 electron in outer shell it is said to be inert. inert gases are called noble gases.
When an atoms loses an electron it?
The atom is said to be ionized. (It can also be said to be oxidised.)
What is the difference between elements and atoms?
An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
What is meant by gain or lose electrons?
The electrons surrounding the nucleus of an atom are in fixed 'layers' - with a defined number of electrons in each 'shell'. Stable atoms have a fixed number of electrons in their outer shell. When two atoms combine (to form a molecule) one electron is 'discarded' and the two atoms share a common electron to keep the molecule stable. The electron that's 'discarded' is said to be 'lost'. The electrons are still present - just 'free-floating'. When two atoms split, they 'grab' a free-floating electron to stabilise the molecule again. This electron is said to have been 'gained'.
What subatomic particles can differ between neutral atoms of the same element?
The subatomic particle that makes atoms of different elements different from each other is the proton. This is given as the atomic number of the element on the periodic table.
What is the meaning of the term isotopes?
An isotope is a form of an element. Isotopes (forms of an element) occur when an atom/s of a single chemical element gains or loses 1 or more neutrons. Eg.. the first isotope "Hydrogen-1" or "Protium" hydrogen has 1 proton in the centre of the atom or nucleus, and 1 electron going around on the outside, isotope two "Hydrogen-2" or "Deuterium" Hydrogen, has 1 proton AND 1 neutron in the nucleus and 1 electron, and isotope three is "Tritium" Hydrogen that has 1 proton, 2 neutrons and 1 electron. The number of protons always stays the same, it's the number of neutrons that determines the form of an element or in other words the isotope.

What is the atoms electron cloud?
The distribution of electron around an atom in various shells is sometimes referred to as electron cloud. If there are more electrons in certain space around the atom, that space is said to have a denser electron cloud.
Who said all elements are made of atoms?
An atom is the smallest unit of any element.
What does an atom represent?
The atomic number is the number of protons in the nucleus. Neutral atoms contain the same number of electrons as protons to balance the electrostatic charge. The number of electrons on an atom will determine its charge, loss of electron(s) will make it positive, gain will make it negative. This occurs when atoms form ions.
What are two elments with the same number of protons but a different number of neutrons called?
Two atoms with the same number of protons are not two elements but one element. If they have differing numbers of neutrons, however, they are said to be of different isotopes.
Who said that each element is composed of extremely small particles called atoms?
